Abstract
Most quark-meson models for formation of a baryon as a bag or soliton solution begin with elementary local meson fields including a classical scalar configuration that provides repulsion of valence quarks from the vacuum. We explore aspects of the very different formation mechanism that operates in a model where chira\ effective meson fields are composite objects generated from bilocal qq fluctuation fields and the dynamical quark mass can be self-confining. Speculations are made on whether this viewpoint can motivate meson-nucleon relativistic field models containing intrinsic cutoffs for use in nuclear physics.
